Cryptocurrencies are property, Singapore court rules, as it freezes US$7m in 'stolen' crypto
Fri, Mar 04, 2022 - 5:39 PM | UPDATED Sat, Mar 05, 2022 - 9:16 AM

SINGAPORE'S High Court has allowed an application by an American entrepreneur to freeze over US$7 million in crypto assets he claims had been stolen by unknown individuals and entities.

In a judgement made public on Friday (Mar 4), the court ruled on 2 novel points of law.

First, cryptocurrencies are a property right and, when stolen, can be be subject to proprietary injunction.

Second, the court has jurisdiction to grant interim orders against defendants with unknown identities.

Crypto exchanges were also asked to disclose information that could help recover the stolen assets.

The court heard that before the alleged theft, the plaintiff, who is unnamed in the judgement, had stored his cryptocurrencies in 2 decentralised wallets accessible through mobile apps via a password or biometric keys.

The wallets can also be accessed using "recovery seeds", which typically comprise a sequence of words.

In January 2021, the plaintiff was on vacation with 7 acquaintances in Mexico.

While he was out one night, the plaintiff called one of these acquaintances to help retrieve cash from his apartment which they were residing. He shared the passcode to access the safe over the phone, and the acquaintance had read it aloud to confirm it.

The following night, the plaintiff discovered that his crypto was withdrawn without his knowledge and consent.

Around 110 bitcoin and 1,498 ether were transferred from the 2 wallets in 3 transactions, within 4 minutes.

This amounted to US$7.09 million based on the value of the cryptocurrencies then.

The plaintiff believes the thieves obtained his recovery seeds by accessing the safe after the acquaintance read the passcode aloud. The plaintiff had sought a proprietary injunction and worldwide freezing injunction against the unknown "thieves".

In the judgment, High Court judge Lee Seiu Kin ruled that cryptocurrencies are recognised as property as they are distinct based on their "computer-readable strings of characters", have exclusive ownership, are "potentially desirable" by third parties, and have "some degree of permanence or stability".

Justice Lee also acknowledged the risk of the defendants further dissipating the stolen assets, which would make it even more difficult for the plaintiff to recover them.

He added that the risk in this case is heightened by the nature of cryptocurrency. "The stolen cryptocurrency assets are susceptible to being transferred by the click of a button, through digital wallets that may be completely anonymous and untraceable to the owner, and can be easily dissipated and hidden in cyberspace," Justice Lee said.

The judge also granted a worldwide mareva injunction that freezes up to US$7.09 million of the defendants' assets.

Justice Lee also ruled that the court can grant interim orders against the defendants even though their identities were unknown when the plaintiff brought his case before the court.

"There is nothing in our Rules of Court that requires a defendant to be specifically named," he said.

The court heard that the plaintiff later managed to identify 2 individuals who are part of the group of crypto thieves and will serve the orders on them via email as their physical whereabouts are unknown.

The plaintiff was also able to trace part of the stolen crypto to 2 wallets held by crypto exchanges based in Singapore but incorporated in Cayman Islands and Seychelles, respectively, a US-incorporated crypto exchange, and a US-incorporated digital payments firm. The 2 US-incorporated entities have wholly-owned subsidiaries in Singapore.

All 4 entities are believed to be "innocent third parties". Nevertheless, the 2 Singapore-based exchanges were ordered to disclose information they had collected in relation to the relevant accounts as well as details of all transactions involving these accounts from the dates the stolent funds were credited against them.

CLM v CLN and Anor [2022] SGHC 46

"...40 The important issue which arose here was therefore whether the Stolen Cryptocurrency Assets, being cryptocurrency, were capable of giving rise to proprietary rights which could be protected via a proprietary injunction.


41 It is apposite to first refer to the classic definition of a property right in National Provincial Bank Ltd v Ainsworth [1965] AC 1175 (“Ainsworth”) at 1248:
it must be definable, identifiable by third parties, capable in its nature of assumption by third parties, and have some degree of permanence or stability.

42 In B2C2 Ltd v Quoine Pte Ltd [2019] 4 SLR 17, the Singapore International Commercial Court held (at [138]–[146]) that it was possible for cryptocurrencies to be held on trust, and that the defendant in that case did hold BTC on trust for the plaintiff. In so holding, the court reasoned that cryptocurrencies meet the four requirements set out in Ainsworth and “have the fundamental characteristic of intangible property as being an identifiable thing of value” (at [142]). However, it should be noted that since this point was undisputed by the parties, the court was satisfied that cryptocurrencies could be created as property in a generic sense and left open the question of what the precise nature of this property right was.


43 On appeal however, the parties disputed the issue of whether cryptocurrencies were a species of property that was capable of being held on trust: see Quoine Pte Ltd v B2C2 Ltd [2020] 2 SLR 20 at [137]. The Court of Appeal reasoned that it was unnecessary to consider this issue because even if it was answered affirmatively, there was no certainty of intention to create a trust on the facts (at [144]). Nevertheless, the court canvassed in detail the authorities in support of treating cryptocurrencies as property (at [139]–[143]):

   139 There have been some other cases in the Commonwealth that have implicitly accepted that cryptocurrency may be regarded as property, although we are not aware of any court that has attempted to identify the precise nature of the property right if any. In Elena Vorotyntseva v Money-4 Limited and others [2018] EWHC 2596 (Ch), the English High Court issued a proprietary injunction preventing the removal of specific ETH and BTC holdings. In coming to his decision, Birss J observed that there had been no suggestion that cryptocurrencies could not be a form of property.   140 In Copytrack Pte Ltd v Wall [2018] BCSC 1709, the Supreme Court of British Columbia ordered that some C$400,000 worth of ETH be traced, which suggests that ETH was recognised as a species of property susceptible to tracing. The action was brought by Copytrack Pte Ltd (“Copytrack”), a company engaged in the business of digital content management and automated copyright enforcement. Copytrack created its own cryptocurrency, Copytrack tokens, and mistakenly transferred a more valuable cryptocurrency, ETH, to the defendant investor instead of Copytrack tokens. The ETH was then transferred by the defendant to third parties. Copytrack sought to trace and recover the ETH. The court characterised the issue of whether the property law doctrines of conversion and wrongful detention could apply to cryptocurrencies as a “critical issue’” and the “real issue on this application”. While the court did not go so far as to rule on whether cryptocurrencies could, in fact, be subject to specific property law claims, the court held that it would be unreasonable and unjust in the circumstances to deny Copytrack a remedy, and so allowed Copytrack to trace and recover the wrongfully transferred ETH.
   141 Academic commentators broadly agree that BTC may be regarded as a property right, although they disagree as to the precise nature of this right. In Jean Bacon et al, “Blockchain Demystified: A Technical and Legal Introduction to Distributed and Centralised Ledgers” (2018) 25(1) Rich J L & Tech 1, the authors suggest (at para 182) that holders of digital tokens such as BTC should be regarded as having a property interest at common law, because they hold a bundle of rights that include the right to control the token. This interest is identifiable through entries on the blockchain, can be transferred by entries of the blockchain, and has a high degree of permanence and stability.
   142 To similar effect is Kelvin F K Low and Ernie G S Teo, “Bitcoins and other cryptocurrencies as property?” (2017) 9(2) Law, Innovation and Technology 235 (available at [color=rgba(0,0,255,1)]https://ink.library.smu.edu.sg/sol_research/2806[/color]), where the authors argue that the property right relating to BTC is the right to have one’s public BTC address appear as the last entry in the blockchain in relation to a particular BTC. Such a right provides exclusive control to the holder in the form of universal exigibility and can be seen as involving a true property transfer when one transfers BTC from one’s public BTC address to another’s BTC address.
   143 Most recently, the UK Jurisdiction Taskforce (‘UKJT’) chaired by Sir Geoffrey Vos released its “Legal Statement on Cryptoassets and Smart Contracts” (November 2019), where it considered the question of whether English law would treat a particular cryptoasset as property. The UKJT defined cryptoassets as generally having the following characteristics (at para 31): (a) intangibility; (b) cryptographic authentication; (c) use of a distributed transaction ledger; (d) decentralisation; and (e) rule by consensus. The UKJT stated (at para 85) that cryptoassets have all the indicia of property, and that their novel or distinctive features as aforementioned do not disqualify them from being property. The UKJT also stated that cryptoassets are not disqualified from being property simply because they might not be classifiable either as things in possession or as things in action. The UKJT therefore concluded that cryptoassets could be treated, in principle, as property.

Ultimately, the court observed (at [144]) that “[t]here may be much to commend the view that cryptocurrencies should be capable of assimilation into the general concepts of property”.


44 The plaintiff referred me to the New Zealand case of Ruscoe v Cryptopia Ltd (in liq) [2020] 2 NZLR 809 (“Ruscoe”), where the High Court held, following a comprehensive discussion (at [102]–[120]), that (at [120]):[C]ryptocurrencies meet the standard criteria outlined by Lord Wilberforce [ie, the four requirements set out in Ainsworth] to be considered a species of “property”. They are a type of intangible property as a result of the combination of three interdependent features. They obtain their definition as a result of the public key recording the unit of currency. The control and stability necessary to ownership and for creating a market in the coins are provided by the other two features – the private key attached to the corresponding public key and the generation of a fresh private key upon a transfer of the relevant coin.


45 In this regard, the court examined the four requirements in Ainsworth in turn:

(a) The first requirement is that the right must be “definable” – the asset must hence be capable of being isolated from other assets whether of the same type or of other types and thereby identified (Ruscoe at [104]). To this end, cryptocurrencies are computer-readable strings of characters which are recorded on networks of computers established for the purpose of recording those strings, and are sufficiently distinct to be capable of then being allocated to an account holder on that particular network (Ruscoe at [105]).
(b) The second requirement is that the right must be “identifiable by third parties”, which requires that the asset must have an owner being capable of being recognised as such by third parties (Ruscoe at [109]). An important indicator is whether the owner has the power to exclude others from using or benefiting from the asset (Ruscoe at [110]). In this vein, excludability is achieved in respect of cryptocurrencies by the computer software allocating the owner with a private key, which is required to record a transfer of the cryptocurrency from one account to another (Ruscoe at [112]).
(c) The third requirement is that the right must be “capable of assumption by third parties”, which in turn involves two aspects: that third parties must respect the rights of the owner in that asset, and that the asset must be potentially desirable (Ruscoe at [114]). The fact that these two aspects are met by cryptocurrencies, is evidenced by the fact that many cryptocurrencies, certainly BTC and ETH, are the subject of active trading markets (Ruscoe at [116]).
(d) The fourth requirement is that the right and in turn, the asset, must have “some degree of permanence or stability”, although this is a low threshold since a “ticket to a football match which can have a very short life yet unquestionably it is regarded as property” (Ruscoe at [117]). In this respect, the blockchain methodology which cryptocurrency systems deploy provides stability to cryptocurrencies, and a particular cryptocurrency token stays fully recognised, in existence and stable unless and until it is spent through the use of the private key, which may never happen (Ruscoe at [118]).


46 Having considered the extant case law and especially the analysis in Ruscoe, I was of the view that cryptocurrencies satisfied the definition of a property right in Ainsworth. The plaintiff was therefore able to prove a serious arguable case that the Stolen Cryptocurrency Assets were capable of giving rise to proprietary rights, which could be protected via a proprietary injunction. I reiterate that the court does not engage in complex questions of law or fact at the interlocutory stage (see [39] above). Hence, the first requirement of showing that there is a serious question to be tried was satisfied..."

How Bitcoin Allowed A Ukrainian Refugee To Escape War And Start Fighting Back On His Own Terms
Shinobi Bitcoin Magazine | Feb 26, 2022

Amid bank freezes and ATM overruns, one Ukrainian escaped with his wealth in bitcoin and is now fighting Russia on his own terms.

You go to sleep one day and wake up the next to find your country is under attack by a foreign power, bombs are falling from the sky in major cities targeting military and critical infrastructure and foreign troops are moving in from all directions. It’s difficult to understand the fear that someone would experience in such a situation, but that is exactly what millions of Ukrainian citizens have been feeling over the past few days.

As of February 24, the Ukrainian central bank suspended electronic cash transfers and ATMs have been overrun. The borders have been closed for all men of fighting age, who have been ordered by the government to stay and fight against Russian soldiers. The government has been encouraging citizens to make molotov cocktails to help fight to defend the country. It's a horrifying situation, and it's beyond words the damage that such things cause for people when they happen.

Bitcoin doesn't fix this, it won't end or undo this situation. But what it can do is function as a tool to help people maintain control over their wealth to survive such a situation.

Protecting Wealth In Times Of War

I was able to speak with a Ukrainian who was able to get across the border to Poland (and am very grateful for his time in speaking to me and others, given the gravity of the situation he finds himself in) who was able to use Bitcoin for exactly this purpose.

For obvious reasons of privacy, during the interview he used the pseudonym “LDV.” He is the webmaster for the company Helios Fund. They take investors' funds and invest in bitcoin and altcoin mining operations, timing altcoin sales for bitcoin at optimal market points so the profits can maintain the operation and be distributed to investors. Helios has paid LDV in bitcoin since he began working for them around a year ago, something that quite literally made the difference between him being able to get out of the country with enough money to survive while he figures out what he is going to do in the long term.

LDV went to the bank before attempting to cross the border to withdraw money — the problem was, he was not allowed to do so. Banks all across the country had shut down ATMs and were not allowing cash withdrawals. This obviously presents a major problem when you are trying to go to a foreign country to escape a military invasion. How will you pay for food, rent or necessities to live your life?

In his case, LDV was able to take some of the bitcoin he had been saving from his salary and sell it to people he knew for cash to acquire around $600 worth of Polish złoty to be able to get by after crossing the border into Poland. Bitcoin was literally the difference between being able to get out of Ukraine with enough money to get by in the immediate term, versus getting out with nothing, condemning himself to a state of total destitution. To paraphrase his own words during my time talking to him, "Without Bitcoin, I probably would not be here talking to you right."

Bitcoin illuminates a very stark dividing line in drastic situations like what is going on in Ukraine right now: the interests of individual people versus the interest of the collective (i.e., the government over its citizens). Obviously, the reason for refusing to process bank transactions is entirely focused on the continuity of government. It's not concerned with what is in the best interest of individual citizens, but what is in the best interest of the government itself being able to continue functioning and financing its operations and defensive efforts against Russian incursion.

Bitcoin is a way to opt out of that choice being made on your behalf. It's a way to make what you economically participate in completely voluntary. It might sound cold, or callous, but it's the reality. In a situation like what is going on in Ukraine, having your wealth in bitcoin makes it entirely your choice whether to take your money and leave — to prioritize your own safety and your family's over the "collective good" of your country or government — or to devote those resources to defending your country and community as the government determines. (The above is not meant to reflect the opinion of LDV or how he is choosing to use his funds, but only to outline the potential bitcoin offers in such a crisis.)

A Refugee Exodus
LDV and his girlfriend packed their laptops, devices and everything required to continue working remotely in order to maintain an income, got in their car and drove to the border with Poland. They made it across the border two hours before it was closed for all males over fighting age (any delay that might have occurred had LDV not had bitcoin, and had he stayed longer trying to find any way to extract fiat from his bank account, could have meant that they would have never made it out).

How did LDV get across the border with his bitcoin? With a USB drive and a piece of paper.

He had been storing his funds with a Tails OS setup on a USB drive, and a word seed recorded on a piece of paper. Is this a secure practice for large amounts of money? No. Is this something that your average Bitcoin user should be doing without taking the time to learn how Bitcoin works, or what they should and should not do with key material? No. But it allowed LDV to cross an international border during a foreign invasion of his country and to get across that border with his wealth intact.

Thanks to Bitcoin, LDV has a buffer budget of cash that was acquired by informally selling bitcoin to carry him through the immediate future of the next week or so. Thanks to the network of Bitcoin ATMs that exists in the world, he has an option to cash out more. Even if those ATMs come with onerous KYC requirements that he can't meet, thanks to the growing prevalence of Bitcoin and the communities of people using it, he has the potential option of finding and networking with those people to directly sell that bitcoin in person for cash in hand. Thanks to Bitcoin, he actually still has some measure of wealth that he is able to use and support himself with, even as a refugee from a war-torn country, instead of being entirely dependent on the charity of the Polish population.

With Bitcoin, LDV was able to flee to a foreign country with the wealth that he was able to save from his job, with multiple options to be able to convert that to the local currency if necessary, as opposed to fleeing with nothing but the clothes on his back and counting entirely on the charity of the people around him when he arrived. That is the power that Bitcoin offers, that is its utility value in a situation where the world around you is literally falling apart.

Safe For Now And Fighting Back
LDV is currently situated somewhere that he can count on stable housing for at least the next week or two, he has the fiat currency necessary to feed himself and meet his basic needs and he has savings in bitcoin that he can cash out into fiat when necessary to handle additional day-to-day expenses. He also has a job that will still provide income, because Bitcoin exists to function as a means of payment that is not disrupted due to the chaos currently erupting in his home country, which will allow him to deal with whatever the future throws at him in these turbulent times without having to entirely depend on the charity of strangers. None of this would be possible without Bitcoin.

Because of this ability to bring his money across the border with him, he is currently assisting a group of hackers that he identifies as "Dmytro," which he claims is responsible for the takedowns of Russia Today and, previously, the Russian defense ministry website. According to LDV, Russian media has claimed that Ukraine attempted to invade Russia. Russian media sites have been targeted by Dmytro in order to prevent the spread of propaganda and false information.

When asked if other, more critical digital infrastructure was under consideration for similar attacks, LDV said that the focus would remain on news and media sites propagating inaccurate information about the current invasion of Ukraine. This might not seem like impactful action, but given the protests occuring in Russia over the invasion despite warnings and harsh consequences for participating in them, and the overall context of the enormous polarization of perception driven by the media in the last few years, it might be more impactful than you might think initially.

All of this is possible because of Bitcoin. LDV was able to get out of Ukraine with his savings, with a regular income that did not disappear because his bank account in Ukraine stopped working, with some degree of autonomy and the ability to pay his own way in a foreign country after having to flee his own with nothing but what he could carry, instead of relying entirely on the charity of strangers with no other option. Bitcoin enabled that. He was able to cross the border between Ukraine and Poland with a USB drive and a piece of paper and with that, transport his wealth and savings along with the clothes on his back.

That is the power of Bitcoin: the power to opt out without having to ask anyone's permission, and in the case of LDV, the power to support and aid Ukraine in its defense against Russia's invasion of his home country — not because he had to, but because he chose to. That's the power of Bitcoin, making it your choice, without having to ask anyone's permission.

The first quantum-safe Bitcoin transaction has been mined
Aug 26, 2026

Avihu Levy’s Quantum-Safe Bitcoin (QSB) method went from research paper to mainnet today. It required no change to Bitcoin’s consensus rules.

A quantum-safe transaction was mined on the Bitcoin mainnet today that holds up against an adversary running a working quantum computer. Bitcoin holders now have a way to move coins into storage a quantum computer cannot open.

Avihu Levy, researcher and General Manager of Applications at StarkWare, designed the method and published the research in April 2026. He built it on his own time, after years spent in the Bitcoin ecosystem. StarkWare engineer Tomer Giladi continued the work to reach the final stretch of a working transaction. Today’s quantum-safe transaction is the first time anyone has run it on mainnet.

People have long assumed that protecting Bitcoin holdings from a quantum adversary would require changing the Bitcoin protocol. Today shows otherwise. A soft fork is still the better long-term answer, as StarkWare has argued for consistently, but it is no longer the only option.
What QSB does

Bitcoin’s signatures rest on elliptic curve cryptography. Shor’s algorithm, running on a large enough quantum computer, will be able to solve that class of mathematical problem quickly, so the puzzle protecting a coin will no longer be sufficient to protect it.

A public key is meant to be public. Publishing one is safe today, because no machine can work backwards from a public key to the private key that made it. A quantum computer can. Once quantum computers exist, every published public key is a private key waiting to be recovered.

Most Bitcoin’s addresses are hashes of a public key, so the key stays out of sight until you spend from that address. The signature reveals it, and the transaction then sits in the mempool in the open until a miner includes it. It is in that window that a quantum adversary could act: read the public key, derive the private key, and spend the same coins first.

QSB closes the window for this type of attack by adding a second quantum-resistant lock alongside the existing one, built on hash functions instead of elliptic curves. Shor’s algorithm cannot break hash functions. The best-known quantum attack on a hash would be to speed up brute-force guessing, but this is not nearly enough to finish the job.

QSB uses signature grinding, a technique that allows you to create a valid Bitcoin signature without a private key, and it works on Bitcoin exactly as Bitcoin exists today. The sender spends computational effort searching for a spending transaction whose hash happens to be a validly formatted signature. Bitcoin accepts it, and the transaction’s security then depends on the difficulty of reversing a hash rather than the secrecy of a private key. That work happens offchain, before broadcast. The approach, which currently costs several hundred dollars, draws heavily on Binohash, developed by BitVM creator Robin Linus.

QSB does not make Bitcoin itself quantum-safe. What happened today is that a specific construction worked on mainnet, and the network is unchanged. The QSB transaction delivers quantum resistance by moving coins into an output that relies on hashes rather than elliptic curves. It would not help an address whose public key was published before the transaction was sent, because an adversary would have time to derive the private key before the transaction was broadcast. Notably, QSB transactions use nonstandard formats, so they will not travel through the ordinary mempool and currently need a direct path to a miner. MARA Slipstream provided that mining path.
How this relates to StarkWare’s work

While StarkWare’s technology is based on ZK-STARKs, which are post-quantum secure, QSB does not use STARKs. It runs entirely inside Bitcoin, built from tools Bitcoin already has. Avihu could have created a solution based on STARKs, which rely on hash functions rather than elliptic curves, but he built what worked on Bitcoin instead.

Every chain faces the same quantum deadline at roughly the same time. Starknet starts with an advantage because STARKs, its proving system, have never depended on elliptic-curve assumptions. Native account abstraction lets a Starknet account change its signature scheme to a quantum-resistant one without a protocol change, which makes migration an account-level decision rather than a governance fight. And post-quantum accounts are already live on Starknet mainnet.

None of that means Starknet is quantum-ready today. StarkWare published a three-phase roadmap in June. Phase one secures all new activity by replacing the elliptic-curve-dependent hashing that remains in state commitments, contract address derivation, and network configuration; parts of it have shipped and parts have not. Phase two extends the same protection to existing contracts. Phase three moves in step with Ethereum, because the bridge that carries messages and assets, and the data availability layer where Starknet posts its data, both still inherit elliptic curve cryptography from L1. The full roadmap is at quantum.starkware.co.

StarkWare CEO Eli Ben-Sasson said, “Avihu took this on after hours, as a passion project, and has now shown that Bitcoin has no expiration date. I still want Bitcoin to choose to do a soft fork and I expect we will get one. What today’s successful transaction offers Bitcoin is a reassurance that holdings can be protected before that happens.”
